Every man wants to bowl well. And let's face it, it's tough. Understanding the physics behind it will help you become a bowling baller. I researched it a bit. Many people know that the lanes are greased, but what most people don't know is that the key to bowling a strike is by hitting between the two front pins, either the 1&2 pins or the 1&3 pins.
It is important to know the use of spin and the conservation of energy and momentum when bowling. The lane has little friction, so you must spin the ball a lot to catch the lane and get that nice curve. Here's where the really physics takes place. The ball contacts the pins, thus creating a chain of collisions between the pins. Without the law of conservation of momentum and energy, when the pins got hit, they wouldn't create the same collisions because momentum would disappear.
Now go hit the lanes champ, you know what to aim for.
